Abstract :
We propose a new semi-analytic method for the study of the performance of a RAKE receiver in a direct-sequence code-division multiple-access (DS-CDMA) based ultra wideband (UWB) system. This method is intended as a tool to facilitate further performance studies of this type of system and, ultimately, to lead to a fully analytical model. We also analyze system performance, in the presence of intersymbol interference (ISI) and narrowband interference (NBI), using two RAKE-based receivers. The first receiver is the classical RAKE, which employs maximal ratio combining (MRC). In the second receiver, MRC combining is replaced by linear minimum mean-squared error (MMSE) combining.
